BACKGROUND OF THE INVENTION

The present invention pertains to deal with artwork manufacturingtechnology. and more particularly, to a vacuum coating plotting method,special device and product.

At present, existing plastic and glass products are generally treated insuch a way for surface coating and design acquisition as to coat theproduct surface completely before getting the design in printing andcorrosion method, etc. For example, the patent application of China No.200610170656.3 discloses a vacuum coating device, method and finishedproducts of forming laser pattern on base material surface, thepolycarbonate base material or the acrylic base material is put into thevacuum coating device mainly, then have the material form a coatinglayer on the surface in vapor plating with silicaon oxides and titaniumoxides, further to arrange the design layer on the other surface of thevapor plated material through printing and distribute another colorlayer on the coating layer; for products coming out of the said method,when the material is irradiated by beams, it will turn out to be in thevisual effect of variable color and refraction of light and shade as thecoating layer refract the light. It can not get hollowing pattern fast,precisely, environmentally protection to use such method.

Presently, for the commonly used vapor plating, sputtering, molecularbeam epitaxy and other vacuum coating methods, the coating deviceusually uses single fixed coating source. However, this device can onlyprocess one product at a time so that it is in low processing efficiencyand can not satisfy the needs of massive production.

For the existing laser etching technology, generally it etches byimporting design data directly, calculate and adjust the design data interms of curvature and roughness, etc. Of the product surface so thatthe acquired pattern will suffer some deformation and is in lowprecision and poor effect.

For products obtained in existing technology, the coating layer isalways on the external surface while product for coating on the internalsurface and hollowing on the coating for plotting hasn't yet been found.

BRIEF SUMMARY OF THE INVENTION

Another purpose of this invention is to provide the device for the saidvacuum coating plotting;

This invention is also intended to provide products coming out of thesaid vacuum coating plotting method, which is a candler.

To achieve these objectives, the invention proposes the followingtechnical scheme:

a vacuum coating plotting method, which adds the following stepsrelativing to the existing adhering membrane technology: pre-treat theinternal surface of the part of such glass embryo body to be plotted forplotting, which comprises Spray a wax layer evenly on the said membrane,then Remove the said membrane, then Perform vacuum coating to the glassembryo body.

The second vacuum coating plotting method: on the base of the existinglaser etching technology, let the laser bean to penetrate the externalsurface of said glass embryo body and scan its internal surface, thenmolten or gasify the coating of said scanned part to make the glassembryo body exposed again and plot it.

The said step also includes following steps:

set an extinction object or shade in the embryo body in advance to stopthe laser bean penetrating the internal side of said embryo bodyprojecting towards other parts, avoiding imprint and damage, which issupposed to exist.

The two said coating layer is aluminum plating layer at the thickness of0.001-0.01 mm, which can meet the require of manufacture and haveartistic effect, better.
